i have to check if an input string is valid based on the given regular expression.. this is the regular expression.

(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)

How To Validate The Length Of A Textarea Using A Regular Expression Validator

May 19, 2010

I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.

Regular Expression Validator Does Not Validate Empty Textbox?

Jun 30, 2010

I would like to validate the textbox for specific text and it must not be blank. But the regular expression validator is not validating if the text box is BLANK. However, it validates if I type something in the text box.

How can I make regular expression to trigger even if the text box is empty?

Should I use Required Validator + Regex Validator at the same time?

<asp:TextBox ID="txtcard" runat="server" MaxLength="16"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server"
ControlToValidate="txtcard" ErrorMessage="Please type credit card no"
ValidationExpression="^d{16}$"></asp:RegularExpressionValidator>
